I'm not sure if there are any translators that allow for US to UK translation, since all of the main translators found on the net are for inter-language translations, whereas US to UK English difference is minimal. There is not much difference between the 'dialects'. If you want you can send me your project and I will try my best to change everything from US to UK English - I am from England . It shouldn't take so long, all it involves is using the Find tool and some fast fingers.
